Feature/banker improvements

[enbytedev]

This pull request builds upon the changes introduced in PR #161 and is branched from that commit.

• Banker Improvements:
  • Percentage Button Functionality:
    • Added two sets of percentage buttons for quick transactions:
      • Player Balance: Allows players to deposit 20%, 50%, or 100% of their wallet balance directly.
      • Bank Balance: Allows players to withdraw 20%, 50%, or 100% of their bank balance directly.
  • Input Validation:
    • The banker will no longer allow negative values to be input.
• Rendering Order Fix in ScreenContinueConquest:
  • Fixed an issue where the background blur effect was being rendered over text. The text now renders clearly above the blurring effect.
